Comment:
This is a simple timestamp precision issue. Input file is 60 fps,
therefore the timestamp of the last frame is *exactly* 5287/60 which is
88.116666666666 (infinite number of sixes), which is indeed smaller then
the outpoint you specified 88.116667 therefore the last frame is not
included. I suggest you round upwards when you specify the outpoint.
